Right, that is probably an error in translation form one of the international developers on the project. (In the File Manager Menu) If you tap on that "Screen server folder" menu item, you will get a message box, named "Screen saver folder" and a keyboard, to enter a path to the folder you wish to use. The path probably should start from /mnt . [The current default location is "/mnt/onboard/screensaver/"]

(In the Reader Menu, the one you get when you have a book open) There is a "Screensaver" menu item. Poking that gives you the option to select "Use this book's cover as screensaver", poking that makes it checked or unchecked. There is also an option to, "Display proportional cover image in screensaver".

The image(s) in the "Screensaver Folder" will be used, if the "Use this book's cover as screensaver" is unchecked or a cover image can't be found. If the user has not defined an image or folder to use, a message box with "Suspended..." will be used.

It looks to be from wherever your "vlasovsoft" folder is. ( For me using KSM7.4, it would be "/mnt/onboard/.adds/vlasovsoft/sleep/", works on my Kobo AuraHD. )

There is a new feature for powering off, with the Power Switch, that gives you a message box with the option to Power Off, if you hold it for 5 sec. (It uses my KSM power off image.)

Luck;
